I was curious. I didn't know what the board was so I went to tindie.com and found the entry. On a hunch, I went over to the PCB manufacturing company oshpark.com and I looked for grbiHAL, and I think I found two boards, one for the Teensy 4.0...
I don't know, you would have to test it out.
Off hand, I imagine that using MTP in the background could affect latency, but who knows. I imagine that when you are transferring files, you are not worried as much about latency, and it won't...
I must admit to not really understanding why you are doing this. Is it a one time operation, or will you need to do this regularly? Can you turn off the Teensy or must the Teensy be running?
To me if it is a one time task, the simplest...
FWIW, I had previously had had arduino-ide_2.2.1_Linux_64bit installed on my Fedora 41 system. I removed the Teensy port, and then I replaced the Teensy json file with the update. I could not get 2.2.1 to show Teensy after doing control-shift-P...
Before the Teensy 4.1 was released, there were a lot of people making PCBs to bring out the SD card and other pins:
OSH park PCB of trainer4edu's PCB without USB host
OSH park PCB of trainer4edu's PCB with USB host
Trainer4edu's board...
If you are using the Teensy 4.0, one possibility is to get the Adafruit Teensy 3.x feather adapter. I'm putting the Adafruit link along with a compatibility page I wrote for the old unofficial Teensy wiki site:
Adafruit Teensy 3.x feather...
Majority of them are postal return. Some have extra solder on the bottom, usually on the 4 slots that hold the USB connector (very likely the USB connector didn't seat properly during reflow soldering and it got some manual rework). A few might...
I'm curious what are likely 'cosmetic' flaws in the 'LEFTOVER_TEENSY_OTHER' item? I mean I will find out eventually when my grab bag gets here. I realize it is a grab bag, and it could be anything, but I was wondering what kind of things were...
Next week PJRC will have a Leftover Teensy Stuff sale, now that SparkFun is manufacturing all Teensy boards.
Teensy 4.0 with pins soldered crooked (but fully functional) at half price will come with a free grab bag of other leftover stuff.
USA...
Cards that are 32GB or smaller are formatted with FAT32 and typically have the VFAT support on top of FAT32 (VFAT adds support for names other than the 8+3 uppercase).
Cards that are 64GB or larger are formatted with ExFat.
It is with dismay that I see this news, just as I was about to launch a product line, based on the Teensy hardware!
My relationship with SparkFun is extremely negative, to say the least; five years ago, my (crooked) business partner, without my...
Well it is free until your program is running. When you call malloc/new, it allocates out of RAM2.
For static/global variables you can use 'DMAMEM' and the variable is put into MEM2. Note, these variables cannot be initialized. I don't recall...
Well in addition to the RAM1 and RAM2 normally that comes with the Teensy 4.1, you have the option to solder 1-2 memory chips to the Teensy.
You can solder 1 or 2 PSram chips
You can solder 1 flash memory chip
You can solder 1 flash memory chip...
I've been idly wondering whether Adafruit will continue to sell Teensies. Now, I realize that Adafruit sells some Sparkfun things, and Sparkfun sells some Adafruit things, and they address different markets. But the change of the supplier may...
